Lights work but nothing else

I just hooked my new 6 volt battery to my 1928 model A coupe but only the lights would work. No starter or horn. I checked the battery and it is fine. Any ideas-suggestions?
 
If everything worked before you put the new battery in, and the new battery checks out OK on a load test, it's probably a ground issue. Unbolt and clean the ground connections. Just my guess

No. The car had been stored in a garage for about 15 years. I got a new 6volt battery and hooked it up. Only the lights work.
 
Does the motor turn over with the hand crank? Horn could be a separate issue - deal with things one at a time but look for disconnected wires and do clean up the grounds. Did you clean the battery cable connections at the battery - really clean them ??? Both starter and horn draw more amps than lights ...
 
Yes, the engine turns over with the hand crank. There is no sound when I try to engage the starter. I will check all of the connections.
 
After setting for 15 years you might have light corrosion in the horn button. On my 28 Phaeton I had to push on the horn button and roll it around to kind of scrape the surface. It didn't take long before it started blowing and has worked fine ever since.

Stock lights draw about 8 to 10 amps, and a well adjusted horn takes about 4 to 5 amps while blowing. The starter will take about 100 amps or a bit more depending on how hard the engine cranks. If you're sure you pressed the starter button hard enough and nothing happened, then give the starter end plate a little tap with a hammer and see if it helps.

Do the lights go out or dim when you step on the starter?
